To all whom it may concern:

Be it known that I, CHARLES K. PIoKLEs, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Nozzles, of which the following is a specification.

The invention to be hereinafter described relates to street flushing or washing devices in which water is stored in and discharged from a movable tank under pressure in such manner as to flush or wash the street, and more particularly it has reference to the nozzle or nozzles employed to effect a proper distribution of the washing or flushing streams.

In flushing or washin devices for street purposes it is essential for the best results that the distribution of water be localized as far as possible and at the same time cover a large extent of street-surface. It is likewise desirable that the streams of water strike the surface of the pavement with considerable velocity at an angle thereto depending upon the character of the surface, to the end that they may have first a scourin and then a flushing effect. Suchstreetflus ing or washing devices are usually mounted on a truck or running-gear, and to be under the more direct control and observation of the operative they are preferably disposed between the front and rear Wheels. While it is desirable to cover as much street-surface as possible with the flushing-streams, it is important that the wheels of the running-gear be not in the stream-path, that the nozzles be near the under central portion of the machine, and that when flushing or washin next the curb the streams do not project a ove the same.

With these various and other general considerations in View that will more fully here inafter appear, one of the objects of the present invention is to provide a nozzle adapted for use on any of the usual or other forms of street flushing or washing machines that will so direct the stream of water that it may have the maximum flushing or washing effect over the greatest extent of street-surface from about the line of travel of the device to a point at substantially right angles to such line, such stream being progressively inclined upward from the front portion of the nozzle toward the rear, so as to cause the stream to first strike the surface near and in front of the advancing nozzle and then be progressively spread to strike the ground at more remote points.

Having the above and other objects in view, as will appear, the invention comprises a nozzle adapted for use as circumstances may dictate, and in the parts and combinations that will be hereinafter more fully described, and definitely pointed out in the claims. 3

In the drawings, Figure 1 is a general side elevation of one type of street flushing or washing machine with the nozzle of the present invention shown as applied thereto. Fig. 2 is a like general plan view of such machine. Fig. 3 is an enlarged detail side elevation of the nozzle, the latter when in use on a machine being adapted to travel in the general direction of the arrow, said Fig. 3. Fig. 4 is ia'plan view of the nozzle, a part thereof being ?broken away and the arrow showing the gen ,eral direction of the travel of the nozzle when in use on a machine. Fig. 5 is a vertical cross-sectionof the nozzle on line 5 5, Fig. 4.

Fig. 6 is a cross-sectional detail on the line 6 6, Fig. 4, showing the inclination of the disicharge-opening at this point. Fig.7 is a like 1cross-section on line 7 7, Fig. 4. Fig. 8 is a I eneral plan view of the nozzle detached om the machine and showing the general character of the flushing and washing stream.

In Figs. 1 and 2, A represents any usual form of water-tank for containing a supply of water under pressure, such pressure in the present instance being supplied from pressure-tanks A A, and, as will be seen from said figures, these tanks are carried upon a suitable truck, the front wheels being preferably closer together than the rear wheels to enable the nozzles to be placed near the median line of the machine and yet not discharge water upon the front wheels. It is to ;be understood that the tanks A and A A are merely selected for illustrating the use of the invention and that other forms of tanks and ,means for sup lying pressure to the watertank might e employed. Likewise the means A A Figs. 1 and 2, for controlling the flow of water from the water-tank through the nozzles may be of any usual or desired character, as they form no direct part of the present invention. Extending from the water-tank A are the discharge-pipes A A to which the nozzles B B may be secured in any desired manner, either adjustably or otherwise.

The nozzle B, Figs. 3, 4, and 5, comprises a suitable casing having an inlet B, provided with suitable connecting means-such, for

instance, as screw-threads-whereby it may be attached to the discharge-pipe of street flushing or washing machines, as shown in Figs. 1 and 2, and the lower wall of said casing is preferably supplied with a screw-plug B which upon removal will enable the interior of the nozzle to be cleaned. The lower to the'median line of the machine and at the same time avoid wetting the front wheels or horses feet and secure proper flushing effect. For this purpose (see Fig.6) the discharge orifice or slot 1), being the one diposed nearest the median line of the machine, is given a general downward incline or slant through the wall or face B as shown by the arrow, Fig. 6, so that water delivered through this orifice or slot will reach the ground in the direction of travel of the machine, but close to the nozzle. It will be noted also that the orifice or slot 1), in addition to being directed downward,- as per arrow, Fig. 6, through the wall or face 13", is inclined upward from front to rear, as between points a a, Fig. 3, the effect being that that part of the fiat stream delivered through the orifice or slot near the point a or nearest the median line of the machine will strike the ground close to the nozzle, while the remainder of the stream will strike the ground progressively farther from the nozzle. The orifice or slot 6 is likewise given a less downward slant through the wall or face 13 (see arrow, Fig. 5) than orifice or slot 1), so that the stream delivered therefrom will strike the ground farther from the nozzle than that from slot 1); but here again the orifice or slot b is inclined upward throughout its length from front to rear, so that that part .of the stream delivered from the portion 0. Fig. 3, of said orifice or slot 6 will strike the ground closer to the nozzle than the portion of the stream delivered from the upper part (1, of said orifice or slot.

The orifice or slot 6 extends through the wall or face B in a less downward slant than either of slots 1) or I). In fact, it may be and is shown in Fig. 7 as being substantially horizontal, so that the stream delivered from orifice b will strike the ground at more remote oints from the nozzle than that delivere from either of slots 1) or b It will be noted also that the slot 6 is inclined upward from end to end between points a of", but at a less angle than either slots 6 or b, the effect Figs. 5 and 6, the flushing or washin figure the nozzle is su of which is that while the portion of the stream delivered from the upperpart 0, of the slot will reach the ground beyond the portion of the stream delivered from the lower portion a of the slot, yet the stream as a whole will be maintained sufficiently low to avoid flushing above the curb, it being understood, of course, that the portion of the stream delivered from the part at of slot b extends substantially at right angles to the line of travel, and any danger of flushing or washing above the curb would depend upon the stream from slot N.

The general effect of the constitution of nozzle having the inclined slots 1), b, and b is to provide a plurality of flat flushing or washing streams progressively spreading to cover areas of l; rger extent from the line of the machine travel to substantially right angles thereto, and by virtue of the less inclination of the rear slot, or that one which delivers substantially at right angles to the machine travel, flushing or wetting above the curb is prevented. By the downward direction given the walls of the slots, as indicated in effect from a point near the median line of t e machine without wetting the wheels or horses feet is further enhanced.

The several inclined slots 6, b, and N, as will be seen from Fig. 3, overlap each other for the purpose of giving increased flushing effect, as well indicated in Fig. 8. In this osed to be secured to the machine to trave 1n the direction of the arrow, and it will be noted that the zone of water 0, coming from the slot 6, strikes the ground or surface close to the nozzle, first at c in line of travel and then progressively far ther from the nozzle to the point a that the zone 0 strikes the ground first at c and then progressively farther from the nozzle to the point 0, parts of the'zones c and c overlapping, as shown. Likewise the water from zone 0 strikes the ground at c and then progressively to the point 0 parts of zones 0 and c overlapping, as shown.

In describing the present invention a nozzle has been selected for illustration and description having three inclined dischargeslots, and these slots have been preferably shown as having their walls radially at difierent angles for directing the water gradually less and less downward from the front to the rear nozzle, where the walls have been shown extending substantially horizontal through the face B but it is to be understood, of course, that the invention is not restricted to either of these details, and while the slots are preferably formed to overlap the invention contem lates other structures reasonably within t e spirit of that described. It is also understood that while the nozzle is primarily designedfor use on a street flushing or washing machine it may be advantageously employed mass in other relations with different forms of a paratus. It will be noted that by the inclination of the slots upwardly from front to rear of the nozzle a very efficient flushing and Washing effect may be secured, and one portion of the stream delivered close to the nozzle while another position may reach the ground a greater distance therefrom, and that by the different angles given the several slots an effective spreading of the water over a large area toward the side of the machine is effected.
